Product Questions & Answers (2)

Question by: Wes F on Mar 23, 2026, 7:05 PM
trying to hook a 1/8-27 npt line into a 0.31 inverted flare port, is that what this elbow is for?
Answer by: Customer Support on Mar 25, 2026, 3:32 PM
For converting between those two connection types, it’s a 90 degree brass adapter with a 1/8-27 male NPTF thread on one end and a 0.31 inch female 42 degree inverted flare on the other.
Question by: Dwight M on Oct 3, 2025, 9:44 AM
Does this fitting work for natural gas lines or just hydraulic stuff?
Answer by: Customer Support on Oct 4, 2025, 4:11 PM
Natural gas is actually one of the listed applications, though it's noted as a special order use case. The fitting also covers hydraulic brake, power steering, fuel lines, and transmission cooler lines. The 1/8-27 male NPT thread pairs with a 0.31-inch 42-degree inverted flare on the female end, and that combination handles a solid range of fluid and gas line configurations. The brass construction holds up well across those applications.
